a bot to scan a channel or whole server for image attachments or urls that might be pixel screenshots, downloads them and checks them for CVE-2023-21036. if it thinks they are it tries to delete the attachment/message. at last it will give out a small statistic with links to messages that it thinks are affected but couldnt delete (e.g. due to permissions)
for detection this uses a script by retr0id https://gist.github.com/DavidBuchanan314/93de9d07f7fab494bcdf17c2bd6cef02 with slight adaptations by https://github.com/infobyte/CVE-2023-21036
the code is mostly horrible and will probably do horrible things if you run it on a large server because the ""ratelimiting"" is very bad. im not responsible if you get your account/bot thrown into the shadowrealm
this needs the message_content intent and a DISCORD_TOKEN environment variable
License
im not sure about the license on the det.py script but cog/acropolypse.py and bot.py are released into the public domain so feel free to use them in your own bot or tweak them to your needs
